Frequently Asked Questions

Is the image upscaler really free?

The 2x upscaler is completely free — no sign-up, no watermark, no limits. 4x AI super-resolution requires a free SaySee AI account.

What's the difference between 2x and 4x upscaling?

2x doubles the pixel dimensions using smart interpolation, great for general use. 4x uses AI super-resolution to quadruple resolution while adding realistic detail and sharpness — ideal for photos and portraits.

What image formats are supported?

We support JPG, JPEG, PNG, and WebP. The output is a high-resolution PNG for lossless quality.

Will upscaling improve a blurry photo?

Yes — especially with 4x AI upscaling. The AI model is trained to reconstruct fine details, reduce noise, and sharpen edges, turning low-res or compressed images into crisp, high-resolution results.

Is there a maximum input image size?

For the free 2x tool, you can process images up to 25MB. For best results, upload the highest quality source image you have.

Can I use upscaled images commercially?

Yes. You own the output image. Use it freely for print, e-commerce, marketing, or any commercial project.
